5.1 This test method is intended for use in the laboratory or field in evaluating distillate fuel cleanliness. 5.2 A change in filtration performance after storage, pretreatment, or commingling can be indicative of changes in fuel condition. 5.3 Relative filterability of fuels may vary...
1.1 This test method is used to measure the bacterial filtration efficiency (BFE) of medical face mask materials, employing a ratio of the upstream bacterial challenge to downstream residual concentration to determine filtration efficiency of medical face mask materials. 1.2 This test...
4.1 Within the present state of the radiographic art, this guide is generally applicable to available materials, processes, and techniques where industrial radiographic films are used as the recording media. 4.2 Limitations-This guide does not take into consideration the benefits and limitations of...
1.1 This test method characterizes the operational performance of cleanable filter media under specified laboratory conditions. 1.2 This test method determines the airflow resistance, drag, cleaning requirements, and particulate filtration performance of pulse cleaned filter media. 1.3 This...
1.1 This practice assures 6.0 log10 removal of retrovirus (for example, MuLV). 1.2 This practice is applicable to monoclonal antibody (mAb), immunoglobulin G (IgG) fusion proteins, recombinant proteins, or other proteins produced using mammalian cell lines (for example, Chinese hamster ovary (CHO),...
1.1 This test method covers the determination of total sediment up to 0.40 ?% m/m for distillate fuel oils containing residual components and to 0.50?% m/m in residual fuel oils having a maximum viscosity of 55 cSt (mm2/s) at 100?°C. Some fuels can exceed the maximum filtration time...
5.1 The presence of water-soluble extractables in membrane filters can create errors in test procedures employing membrane filters. However, these errors can be eliminated or significantly reduced if the quantity of water-soluble extractables of the specific membrane is previously determined....
1.1 This test method covers the determination of the rate at which a layer of clay-water paste is formed from a clay-water slip under pressure filtration. The filtration rate is directly related to such whiteware operations as filter pressing, slip casting, and drying of ware in which...
1.1 This test method measures the amount of fine particles adhered on plastic pellets or granules in which they are commonly produced and supplied. The lower limit of this test method is restricted only by the porosity of the filter disc used to capture the particle size being quantified. 1.2 The...
1.1 This test method measures the aerosol filtration performance of porous packaging materials by creating a defined aerosol of 1.0 μm particles and assessing the filtration efficiency of the material using either single or dual particle counters. 1.2 This test method is applicable to...
5.1 The effectiveness of antimicrobial agents incorporated into disinfectants, sanitizers, and antiseptics is measured by their ability to kill microorganisms within a specified contact time. Hence, accurate determination of antimicrobial effectiveness requires complete and immediate inactivation...
1.1 This specification is intended to help ensure barrier face coverings meeting the stated requirements provide (1) a means of source control for individual wearers by reducing expelled aerosols from the wearer's nose and mouth into the air; and (2) a degree of particulate filtration that...
1.1 This specification is primarily intended to help ensure barrier face coverings meeting the stated requirements provide (1) a means of source control for individual wearers by reducing the number of expelled droplets and aerosols from the wearer's nose and mouth into the air; and (2) to...
1.1 This test method covers an engine test procedure for the measurement of the effects of automotive engine oils on the fuel economy of passenger cars and light-duty trucks with gross vehicle weight 3856 kg or less. The tests are conducted using a specified spark-ignition engine with a...
1.1 This test method may be used to determine the initial, fractional, filtration efficiency of household and commercial canister (tank-type), stick, hand-held, upright, and utility vacuum cleaner systems. 1.1.1 Water-filtration vacuum cleaners which do not utilize a replaceable dry...
1.1 This test method covers the determination by filtration time after cold soak for the suitability of biodiesel fuel blendstock (B100) that meets all other requirements of Specification D6751 and has a cloud point below 20?°C (68?°F) to provide adequate low temperature operability...
1.1 This guide provides recommendations for the selection of appropriate test methods for prefabricated vertical geocomposite drains (sometimes referred to as wick drains) used in geotechnical engineering applications to provide consistency in data reporting. 1.2 This guide includes test methods...
This SAE Aerospace Recommended Practice (ARP) describes the multi-pass method for evaluating the filtration performance of fine lube filter elements, commonly utilized in aerospace power and propulsion lubrication systems: gas turbine engines, auxiliary power units (APUs), helicopter...
5.1 Microbiological water testing procedures using membrane filtration are based on the premise that all bacteria within a specific size range will be retained by the membrane filter used. If the membrane filter does not retain these bacteria, false negative results or lowered density...
1.1 This specification covers the special grade of industrial woven wire cloth, referred to as filter cloth, for general filtration including the separation of solids from fluids (liquids or gases), based on a desired particle size retention. Filter cloth can be made of any primary metal or...
